Building Malaria Modeling Capacity in Sub-Saharan Africa
The basics of malaria
Biology and epidemiology: Malaria is an entirely preventable and treatable disease. It is caused by a protozoan parasite of the genus Plasmodium and is transmitted from person to person by Anopheles mosquitoes. There are over 400 different species, but only 30 are important vectors of malaria.
Five species of the genus Plasmodium can infect humans. Two of them, P. falciparum and P. vivax, pose the greatest threat. Although P. vivax can cause acute and fatal infection, P. falciparum is the most dangerous malaria parasite. It is also most prevalent on the African continent and is responsible for most malaria deaths.
INDICATOR: Incidence of malaria and mortality rate due to this disease
1- Global Progress
In 2000, more than 80% of cases and 90% of deaths occurred in sub-Saharan Africa, where children under 5 were particularly vulnerable to the acute and fatal form of the disease.
2- challenges to overcome
Despite the spectacular progress recorded in sub-Saharan Africa and even if deaths due to malaria have been avoided more than elsewhere, it is in this region of the world that the disease is most severe. In 2015, it was estimated that the 15 hardest-hit countries, most of which are in sub-Saharan Africa, alone accounted for 80% of malaria cases and 78% of deaths. The decrease in the incidence of the disease in these 15 countries between 2000 and 2015, of 32%, remains far behind that observed in the other 54% countries. Declining incidence must be greatly accelerated in these countries to improve global progress.
3- Proportion of children under 5 sleeping under insecticide-treated mosquito nets,
Progress made:
The indicator is analyzed only for sub-Saharan Africa, where malaria mainly affects children under 5 and mosquitoes mainly bite at night.To guarantee the protection of the most vulnerable populations, the indicator must reach high values, ideally 100%.
4- Achieving and sustaining universal coverage: two phases, two goals
• Scaling up interventions for real impact: during this phase, the goal is to rapidly achieve universal coverage for all at-risk populations through locally adapted, health systems-based malaria control interventions reinforced.
• Sustained control: during this phase, the objective is to maintain universal coverage through the constant strengthening of health systems, until universal coverage is exhausted by elimination or until research in the field suggest that it can be reduced without risk of resurgence of malaria.
The scale-up and sustained control phases share two main activities: strengthening systems to enable malaria control and expanding and sustaining universal coverage with appropriate interventions. These two complementary activities begin with the scale-up phase and continue into the sustained control phase to ensure continued reduction in mortality and morbidity.
FIGHT AGAINST MALARIA
Achieve universal coverage with tailored interventions. Scaling up interventions and maintaining universal coverage (100%) of appropriate interventions for the entire population at risk with a target of at least 80% utilization will lead to a considerable reduction in morbidity and malaria mortality.
PREVENTION:
Universal coverage for prevention means that 100% of the population at risk receives appropriate preventive interventions given the local context. For these interventions, coverage is defined as follows:
• Long-lasting insecticide-treated mosquito nets (LLINs): A household should have one long-lasting insecticide-treated bed sheet for every two people living in the household.
• Indoor residual insecticide (IRS) spraying: the interior walls of each dwelling are systematically sprayed with an effective insecticide, respecting the appropriate interval between two sprays.
• Intermittent preventive treatment (IPTp): A pregnant woman living in an area with high transmission receives at least two doses of an appropriate antimalarial during her pregnancy.
• Other vector control interventions: other targeted approaches (eg larviciding and environmental management, etc.), based on scientific evidence, are used where appropriate.
CASE MANAGEMENT: Universal coverage means that 100% of patients receive appropriate case management interventions given the local context. For these interventions, coverage is defined as follows:
• Diagnosis: A patient receives rapid parasitological confirmation of the diagnosis of malaria (by microscopy or rapid diagnostic test [RDT], with certain exceptions).
• Treatment: An infected person receives the appropriate antimalarial treatment for uncomplicated or severe malaria within 24 hours of onset of illness.
Careful attention is needed to ensure that interventions reach the most vulnerable populations and that gender (male/female), socio-economic status or geographic location is not a barrier to accessing these interventions.
●The vaccine, a safe and effective way to fight against malaria.
Strengthening health systems to enable the fight against malaria and to achieve and maintain universal coverage requires considerable effort.
Support element 1: Take advantage of innovation and develop research.
Supporting element 2: Making the environment more favorable
IDEAL, OBJECTIVES AND PRINCIPLES is that of a world without malaria or zero malaria
PROPOSED POLICY FRAMEWORK:
Until new tools and improved approaches arrive, we urgently need to adopt the recommended set of strategies and expand their application to improve the effectiveness of interventions and end preventable deaths from malaria.
● Development of a schedule for the work system, namely:
─ Organize work, meeting, conference and training sections
─ Plan the field work.
● Training of community champions and insecticide spray technicians to support the program.
● Awareness campaign to support the zero malaria program through:
─ The media, TV channels and radio broadcasting
─ Billboards, advertising on buses for a period of two months.
─ Massive distribution of program brochures to the community
─ Organize film screenings
─ Coordinate work with the health system
─ Create a network of people working for change.
● Organization of the work process:
─ Community champions should bring a Kit: a backpack, long-lasting insecticide-treated bed nets and pharmaceuticals for malaria prevention, a smartphone, communication equipment and a salary.
─ Mosquito control technicians, divided into groups or cells, supervising a section chief, will be distributed in the following areas: towns, villages, countryside and farms.
● Duties: Locate and treat larval areas or mosquito breeding areas.
Apply the residual insecticide spray inside the premises: dwellings, public places, etc.
Means of transport: car, motorcycle and tricycles
● in conclusion, the success of this project will depend on the innovation and the type of financing for a zero malaria world.
Health systems are complex entities with many stakeholders, including patients, doctors, hospitals, medical providers, purchasing organizations, regulators, public authorities and the population as a whole. . These stakeholders are linked by a series of relationships
based on mutual accountability
Intervener: public authority
Example of needs:
- Monitor the health status of the population
- Determine health policies
- Ensure the proper functioning of procedures
regulatory
- Ensure that public funds are used as the
wanted the authorities
- Ensure that the information functions
and appropriate research are put in place
- Study the degree of effectiveness and efficiency of laws and
regulations
Data needed:
- National performance information
and international
- Information on access to care and equity in the provision of
care
- Information on the use of services and deadlines
waiting
- Population health data
- Regulators
We are of African origin, and compared to the world, Africa suffers from a triple burden of communicable, non-communicable and socio-behavioural diseases, to which must be added illiteracy, poverty and underdevelopment. It generally ranks last in all health and development indicators.
Health indicators in sub-Saharan Africa are among the worst in the world. They testify to the poor performance of the approaches used so far.
We demonstrate this with the example of malaria, which is the leading cause of consultation and hospitalization in most countries of the region, despite the appreciable efforts made by countries to reduce the burden of this condition over the last decade and which are beginning to show encouraging results. Looking closely at health systems efforts in the region, it is clear that the emphasis is on strategies that focus on disease as a distinct entity unrelated to socio-economic development.
Our programs focus mainly on the diagnosis and treatment of diseases with prevention components which themselves fall within the field of disease and not health (community awareness program from a preventive point of view, for example: use of insecticide-treated mosquito nets, treatment of outbreaks by spraying with residual insecticides, etc.) Conferences with changes of ideas, planning.
We encounter in our journeys with the communities the following questions:
Can we really reduce maternal mortality without reducing poverty, without educating women and without empowering women? Or will we be able to reverse the downward trend in tuberculosis without reducing poverty for a disease strongly correlated with it? Is infant mortality not just as strongly associated with the level of education of the mother?
The answer is unequivocal and calls for a rescaling of disease control strategies. In this sense, it is important that the region's health systems learn to understand the strategy of “health in all policies”, one of the five pillars of health promotion. This will enable them to take full advantage of the many resources already existing and invested in other sectors such as education, urban planning, agriculture, water and sanitation, public works and transport, employment, etc.
- Employ unconventional or proxy data sources to inform primary health care performance improvement
- Provide improved measurement methods that are low cost, fit-for-purpose, shareable across information systems, and streamlined for data collectors
- Leverage existing systems, networks, and workflows to streamline the collection and interpretation of data to support meaningful use of primary health care data
- Provide actionable, accountable, and accessible insights for health care providers, administrators, and/or funders that can be used to optimize the performance of primary health care
- Balance the opportunity for frontline health workers to participate in performance improvement efforts with their primary responsibility as care providers
- Growth
We postulate this challenge on 6 main elements in the context of strengthening health systems:
1. Leadership and governance. This includes strong political commitment to the fight against malaria, clear definition of policy and funding frameworks in line with international recommendations, regulations, leadership and support from national authorities to carry out planning efforts. and coordinate
and align all partners.
2. Sustainable financing and social protection. It is essential that malaria programs have access to adequate resources at the right time for planned activities, to ensure that populations at risk are covered by the required interventions without excessive personal contribution.
3. Health personnel. Sufficient numbers, well-trained, well-distributed and productive staff are needed to deliver the highest quality interventions possible.
4. Medical products, technologies, infrastructure and logistics. Effective and cost-effective prevention and case management tools must be made available to all at-risk populations.
5. Provision of Services. Good health services are those that provide effective, safe and quality interventions to the people who need them, when and where they are needed, with a minimum of waste of resources.
6. Health information system. The health information system ensures the production, analysis, dissemination and use of reliable and up-to-date information. It includes monitoring and evaluation, disease and mortality surveillance, disease mapping and information technology.
